While this is a relatively new area of study in the media landscape, the use of machine learning and artificial intelligence has increased substantially over the last few years. In particular, the adoption of data science models for personalization and recommendation has attracted the attention of several media publishers. Following this trend, this paper presents a research literature analysis on the role of Data Science (DS) in Digital Journalism (DJ). Specifically, the aim is to present a critical literature review, synthetizing the main application areas of DS in DJ, highlighting research gaps, challenges, and opportunities for future studies. Through a systematic literature review integrating bibliometric search, text mining, and qualitative discussion, the relevant literature was identified and extensively analyzed. The review reveals an increasing use of DS methods in DJ, with almost 47% of the research being published in the last three years. An hierarchical clustering highlighted six main research domains focused on text mining, event extraction, online comment analysis, recommendation systems, automated journalism, and exploratory data analysis along with some machine learning approaches. Future research directions comprise developing models to improve personalization and engagement features, exploring recommendation algorithms, testing new automated journalism solutions, and improving paywall mechanisms. |  |\n\n1. Introduction  \nDigital innovation introduced a dramatic change in media companies. The decline of print advertising revenue, the distribution of free digital content and the change of reader’s behavior induced a need of new sources of revenue (Arrese, 2016; Rußell et al., 2020). Subscription business models, usually in the form of paywall models (Pattabhiramaiah et al., 2019; Rußell et al., 2020), become a solution to assure companies’ sustainability (Davoudi & Edall, 2018; Simon & Graves, 2019). Consequently, high level data-based Expert Systems models have emerged (Davoudi et al., 2018).  \nCurrently, each second of time results in millions of readers interacting on digital platforms, which provides huge volumes of data to be collected and stored by media companies (Lewis, 2015). This new Big Data era in Journalism demanded the development of new technologies and brought Data Science (DS) and Artificial Intelligence (AI) capabilities to the newsroom (Borges et al., 2021). Moreover, the adoption of  \nMachine Learning (ML) methods is mentioned in the Reuters Digital Report as the new trend in media companies, especially for personalization and content recommendation (Newman et al., 2019; Yeung & Yang, 2010; Zihayat et al., 2019). Comment analysis, event mining, and journalism automation have attracted a great attention and nowadays continue being an outstanding research area.
